Nakauriite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Cu8(SO4)4(CO3)(OH)6 · 48H2O
May contain minor Mg, Ni.
Colour:
Translucent blue
Crystal System:
Orthorhombic
Name:
Named for the type locality.
The originally reported sulphate content appears to be questionable according to several literature sources; the crystal structure is unknown. Palenzona & Martinelli (2007) suggest a formula (Mg,Cu)x(CO3)y(OH)z•nH2O (x, y, z unknown).
